...Database management system (DBMS) A database management system (DBMS) is a program, or a collection of programs, through which users interact with a database. The actual manipulation of the underlying database is handled by the DBMS. In some cases, users may interact with the DBMS directly. In other cases, users may interact with programs such as those created with Visual Basic, Java, Perl, PHP, or C++; these programs, in turn, interact with the DBMS, as shown in Figure 1-9. In either case, only the DBMS actually accesses the database. It typically supports query languages, which are in fact high-level programming languages, dedicated database languages that considerably simplify writing database application programs. Database languages also simplify the database organization as well as retrieving and presenting information from it. A DBMS provides facilities for controlling data access, enforcing data integrity, managing concurrency control, recovering the database after failures and restoring it from backup files, as well as maintaining database security. Entity An entity is a person, place, object, event, or idea for which you want to store and process data. The entities of interest to Premiere Products, for example, are sales reps, customers, orders, and parts. Attribute, Column, Field An attribute is a characteristic or property of an entity.

...Assignment 1: Business Rules and Data Models A database is an incorporated PC structure that stores end-user information and metadata (Leake, A.). Data is the raw format of information, which when structured properly, it can produce accurate, relevant, and timely information that is the key to making a good database management system. The true purpose of a database is to provide computer-based systems a way in which to store, manage, and retrieve data quickly. A local college has tasked me to develop a database that will keep track of students and the courses that they have taken. In addition to tracking the students and courses, the client wants me to make the database keep track of the instructors teaching each of the courses. The local college database, will be to store the data of enrolled students, the courses offered and class schedule, and the information of the instructors. The database will provide course matches for each student based off previous courses taken and pre-requisites obtained, as well as keep track of the instructors that are teaching the class. The database will provide the data a student needs to insure they are taking the correct courses and provide the college and the faculty general student information, such as student ID. Entities (Tables) are defined as a person, place, thing, or event in which data is collected and stored. Each entity is a unique object that may be a physical or abstract object within real life (for example:...

...Assignment 1: Business rules and Data Models CIS 111: Introduction to Relational Database Management Systems Purpose of Database Spellman University had requested that I develop a database for their college. The purpose of the database will be to track the students and the courses. There also will be a place in the system to track the instructors teaching each course. There are many things to be considered in composing this database. This paper will outline the entities, attributes for each entity, the type of relationship, constraints, some business rules, and the conceptual and physical models. Entities and Attributes of Database There will be three main entities in the system; the students, the instructors and the courses. The students’ attributes would be last name, first name, social security number, and phone number, date of birth, address, student ID, level of education, enrollment date, GPA, any standardized test scored, all accepted credits, and their class schedule. The attributes for the instructors would be last name, first name, teacher ID, salary, address, telephone numbers (and or extensions), certifications, degrees, and the course code that they will be teaching. The courses attributes would be a specific course code. Along with the course code each individual class would have to have a code as well. This would make the system easier to keep track of instead of having it spelled out next to either the instructors' or the student's name. The relationship...

...he problem with Compaq is that they developed too much IT architecture using financial advisory, where R&D and openness keys to development and the culture, while ignoring the environment. Open communication and trust was barricaded and destroyed by ASK (financial IS). The workers were being motivated by fear, much like Geneen in Morgan’s Images Of Organization. From an IT architecture standpoint, numbers based on the finance division depicted the entire company, even the organizational structure. The organizational structure did not align with the IT architecture, and the culture did not align with it either. Morgan stated, “The division of labor characteristic of industrial societies creates a problem of integration, or what may be more accurately described as a problem of integration, or what may be more accurately described as a problem of “cultural management.”” Compaq started as a functional structure, changed into a divisional fairly soon and then back to functional. Culture was strongly emphasized over anything else. CASH stated, “The process encompassed a whole range of ideas, including (1) the rule of inclusion, (2) teamwork, (3) “working the issue,” and (4) consensus building.” The IS system at Compaq did allow the free-flow of information through email named “B-mail.” ASK was used for financial services so that the company could easily track orders, and know where it stood financially. The culture felt monitored by ASK operators since it “becomes responsible for...

...The Advantages of a relational Model According to ACME Global’s website the mission of ACME Global is to “Help clients achieve profitable growth by aligning and improving customer facing processes and by continually seeking ways to improve operational performance"(“ACME Global,”2014) Because of your consultants over 100 clients maintain successful business with financially and operationally sound strategies. To continue this success and expand on that success a relational model would be easy to use. The revision of any information as tables consisting of rows and columns is much easier to understand. This would play a vital role in organization of not just your consultants but when you stop and look at your clients and the data you are responsible to managing along with the common data and information you want to know. An E-R Model provides Flexibility: Different tables from which information has to be linked and extracted can be easily manipulated by operators such as project and join to give information in the form in which it is desired. This would be most beneficial to you when you look at your areas of Strategic Development and Business planning, marketing & Sales Strategy and your Operations and Organization Management. In all of these are areas are key data and resources of ACME Global that would be enhanced by using a relational model. Purpose of an E-R Model Specific to ACME Global Consulting ACME Global along with your partner Deegit, Inc. deliver innovative...

...Title: Pain, Coping and Sleep in Children and Adolescents with Sickle Cell Disease (Quantitative?) Abstract: Purpose The study examined the relationships among pain, pain coping, and sleep, and assessed factors (age, gender, frequency, and intensity of pain) that affect pain, coping, and sleep in children with sickle cell disease ( SCD). Methods Participants (66) were 39 children ( M = 11.5 years) and 27 adolescents ( M = 15.5 years) with SCD who completed an electronic visual analog scale ( eVAS), Pain Coping Questionnaire, and Pittsburg Sleep Quality Index. Results About two-thirds of the children reported pain the previous month. No significant differences were found between pain and age, gender, pain intensity, or frequency. Most children coped with pain by seeking information, problem solving, seeking social support, and positive self-statements. There were significant negative correlations in males between worse pain severity and behavioral distraction and internalizing or catastrophizing. The majority (91.2%) had mild to severe sleep disturbances, with 18.2% requiring sleeping medication three or more times a week. There were no significant differences between sleep and age, gender, pain intensity, or frequency. Conclusion Children with SCD experience pain that affects sleep patterns and the way they cope with pain. Nurses need to concurrently assess pain, coping, and sleep and promote sleep hygiene and positive coping strategies during pain episodes. Graves, J. K....

Donald Béliveau Université Laval Comme exigence partielle pour le cours MRK-6087 : Politique de prix Par Tébéreye Bâ 111 062 283 Arlette Gounouo 111 063 138 Félix Létourneau 909 331 414 Salomé Thériault 111 073 071 Le 18 septembre 2013 Question 1 : En utilisant un modèle, montrez de quelle façon la valeur économique pourrait être calculée pour ce produit. Veuillez faire toutes les hypothèses qui sont pertinentes. Pour estimer la valeur économique de notre produit, nous avons utilisé le modèle "Value-based pricing" proposé notamment par les auteurs Nagle, Hogan & Zale (2011). Cela consiste à identifier le prix de la meilleure alternative à notre produit, à évaluer tous les gains supplémentaires que procure le produit pour le consommateur, autant monétairement que psychologiquement, et finalement à soustraire les différenciations que ce dernier perçoit comme étant négatives. Dans notre cas, le produit offert est un système qui permet d’éviter une surtension des compresseurs qui pressurisent et dirigent le gaz vers les "pipelines". La valeur de notre produit est donc basée sur le fait qu’il diminue le risque (nombre) de surtensions. Ceci permet aux clients d'éviter des pertes de production potentielles et des coûts supplémentaires. Lorsqu’il n’y a aucun mécanisme de contrôle, on estime que par année, il y a 0.4 surtension mineure et 0.004 surtension majeure...
